The plan calls for work to begin simultaneously in Northwest, Northeast and Southeast. The 60 lines to be buried underground stretch through Wards 3, 4, 5, 7 and 8 and would affect neighborhoods, including Chevy Chase, Cleveland Park, Fort Totten, Brookland, Benning Heights and Anacostia.

City officials say these distribution lines have been responsible for the city’s worst power outages.

D.C. Department of Transportation Director Terry Bellamy says there would be some digging on major arteries, but most of the work would be in the neighborhoods.

“We’ll be working a lot on … residential streets and minor arterials,” Bellamy says.

The project would not be anywhere near as disruptive as Metro tunnel and station construction.

“What we are talking about is about a 3-foot deep, 4-foot wide … trench for Pepco,” Bellamy says.

Manholes will be dug at key locations, a little deeper than the trenches.

Gray says to limit disruptions, efforts would be made to coordinate the work with the schedule of street repairs.

“If DDOT is going to be working on 16th Street, that presents the opportunity to do any undergrounding on 16th Street,” Gray says.
